Android 实现图片的圆角,倒影,转换
2010-11-05 00:54:52 来源:WEB开发网import android.os.Bundle;
import android.widget.ImageView;
public class Imagedemo extends Activity {
private ImageView mImageView01,mImageView02;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
setupViews();
}
private void setupViews(){
mImageView01 = (ImageView)findViewById(R.id.image01);
mImageView02 = (ImageView)findViewById(R.id.image02);
//获取壁纸返回值是Drawable
Drawable drawable = getWallpaper();
//将Drawable转化为Bitmap
Bitmap bitmap = ImageUtil.drawableToBitmap(drawable);
//缩放图片
Bitmap zoomBitmap = ImageUtil.zoomBitmap(bitmap, 100, 100);
//获取圆角图片
Bitmap roundBitmap = ImageUtil.getRoundedCornerBitmap(zoomBitmap, 10.0f);
//获取倒影图片
Bitmap reflectBitmap = ImageUtil.createReflectionImageWithOrigin(zoomBitmap);
//这里可以让Bitmap再转化为Drawable
// Drawable roundDrawable = new BitmapDrawable(roundBitmap);
// Drawable reflectDrawable = new BitmapDrawable(reflectBitmap);
// mImageView01.setBackgroundDrawable(roundDrawable);
// mImageView02.setBackgroundDrawable(reflectDrawable);
mImageView01.setImageBitmap(roundBitmap);
mImageView02.setImageBitmap(reflectBitmap);
}
